+// walks up to us. Forwarding to [super pressesBegan:] re-enters
+// UIViewController's default chain walk, which on iPhone / iOS 26.4.2
+// hangs the next inbound key delivery (the user sees a focused field
+// where typing does nothing and the rest of the app freezes -- see
+// #5010). Returning early keeps the override fully transparent while
+// editing and preserves HW-keyboard support (#3498) for non-editing
+// state. The keyboard NSLog calls are intentionally left in for #5010
+// diagnostics; volume is bounded because pressesBegan only fires on
